Aster yellows doesn’t strike often — but when it does…

November 21, 2012

Yes, 2012 was a bad year for aster yellows in canola, but we have to keep this disease in perspective. Sclerotinia and blackleg are potential threats each year, and remain the top two most important canola diseases. Aster yellows has had only four bad years on the Prairies to date: 1957, 2000, 2007 and 2012.

By Albert Parsons November 9, 2012

Maybe it was because of the lovely warm, sunny autumn that we enjoyed, but for whatever reason, retail shops and garden centres were filled with potted chrysanthemums in the weeks leading up to Thanksgiving. Even after Thanksgiving, there was an abundance of potted mums available for people to use in their autumn décor. The colours

Fall tree planting

By Albert Parsons October 10, 2012

A couple of years ago I splurged and bought a tree, a “Purple Spire” crabapple. I put a lot of thought into choosing the location for the tree but alas, like so many gardening plans, this one did not go as intended. Since planting the tree, I have had to take out my mature mountain

Some weeds are toxic for horses

By Carol Shwetz September 22, 2012

In natural settings, horses develop selective grazing habits, seeking out healthy grasses and forages and avoiding those that are harmful. Relatively few plants are poisonous to horses and, fortunately, horses tend to avoid eating these because of their low palatability. Horses with an abundant supply of quality pasture or hay avoid temptation to select harmful

Sucking instead of blowing to seed canola

By Alexis Kienlen August 10, 2012

A group of researchers is testing to see whether it’s better to suck than to blow when seeding canola. They’re experimenting with a vacuum planter, which works opposite to an air seeder — a vacuum pulls seeds into rotating plates which place the seed into the soil. The attraction is seed “singulation” — the ability

By Albert Parsons August 10, 2012

Coleus have long been an important component of shade plantings; whether planted in the ground or grown in containers, they have traditionally been popular plants for those spots in the garden that receive little direct sun. The older varieties, such as the “Rainbow” series, are all suitable for use in the shade and in fact,
